Hi all,Figure I might as well study up before I get this stuff. I'm interested in the claims made on behalf of ERS sheets, but I remain skeptical. $30 isn't a big deal, though, so I think I can afford to experiment. Some questions and propositions for experienced users, then:
The impression I get is that carefully delimited use of the sheets is best. True of anything, I suppose, but it seems to be especially true in this case. How small a piece are we talking about for most applications? When people say they "put some on [their] CD player," what's "some"? Like a whole sheet? A 2" square? What? And as far as CDP's go, I've read descriptions of affixing it to the inside of the chassis...is this wise? Where should you put it--above the clock? Some place else? Someone, unless I misread them, even said they set a piece *on* their clock. Is *that* wise?
My idea, based on recommendations, is to put some probably 'on' my CDP, whatever that amounts to, and to put some at the ends of my cables, which brings me to my other barrage. Should you put some on both ends of every cable, or does it work better on one or another particular end? *Why* does this work? Anybody have experience putting some on crossovers? In the case of AC cords, do you put it on the actual plug, or on the cord right next to the plug? Similar question as far as IC's or speaker cable--right on the jacks/binding posts, or on the cord next to the actual connection?
In short, what the hell should I do with this stuff once I get it? And does anybody know why it works?
Much obliged for the indulgence. Thanks for any suggestions.
Follow Ups:
I adhered a whole sheet underneath the top side of my CD player, then I covered the small transformers inside, being careful to electrical tape the edges of the ERS so I wouldn't zap anything. I also did the same thing for my preamp/processor. Then I took another sheet, cut it into pieces large enough to cover the area above the transformers in my amplifiers. I laid this on top of the amps, not inside.It was a nice improvement, a lowering of the noise floor. Well worth the 20 bucks for a sheet.
I covered my power conditioners, that was probably the biggest improvement. They are very large (5kv each) isolation tranformers wired for balanced AC. I hear that wrapping your AC cords makes a similar improvement. That is easier now with the ERS tape. Cryotweaks.com has the 1/2" and the 1" tape available. I haven't wrapped any cords myself. But that is my next experiment.
I also cut a sheet into 3/4" strips and wound it around a set of interconntects. That was a very subtle improvement. I have JPS labs Ultraconductors, and the shielding may already have been adequate for my situation.Everyones mileage may vary on this, the thing is you have to experiment. The best places to start are digital sources, and your AC.
Keep us posted on your results!
That's pretty much what I was thinking, concentrate on the AC and digital. Sounds like you were pretty liberal with it then? Do you think it's easy to go into overkill?
Working on the AC and digital, not so much. The interconnects can have the life sucked out of them if you are too liberal.Good Luck!
I have tried the ERS and it seems to work everywhere more or less. What do you mean by "have the life sucked out of them". This term gets used a lot. Do you mean that it changed the perceived frequency balance and you do not like the change? I'm not trying to challenge your ears, just trying to prompt some discussion about this topic. I have had this effect happen in my system many times with different tweaks. What I have concluded is that changes in perceived frequency balance are easily controlled. If the tweak provides new low level information previously unheard then it is a good one, if it merely changes the percieved balance then it is nor worthwhile. What often happens is that the improvement makes other flaws in your system more apparent.
Here goes. When I say the life has been sucked out of the music, I mean that not only background noise is gone, but even some of the musical information seems to disappear as well. It could be just a drop in the critical midrange frequencies. The ambient echos and long instrumental decays in a recording that were once heard are now gone. That to me is the "life" in the recording. Perhaps you and others call it something else.Does that help?
